m
where "t" is in seconds.
(i) What are the positions of the objects at t = 0, 1, 2, 3, 4 and 5
(ii) What is also the average speed between t = 0 and t = 2​

That would be the corect answer hope this

The best answer is (a) which is universal law is in effect at all times. it is constantly at play in everything we do and governs our lives. it is also important to note that universal law applies to not only everything on earth, but everything in the universe as well, which is another reason why it is in effect at all times.

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )
